Does any one have an explanation as to why all miter saw miter scales
show (0) Zero where it should say 90 degrees? They all show zero and
go towards 45 degrees, instead of 90 degrees going towards 45 degrees.

If anyone has an explanation it is probably also good for why the
bevel scale is the same way.


Reference planes. A 90 degree cut is referenced off the fence, while
the 0 degree cut is referenced off the normal track of the blade.

I personally find it easier to work off of a 0 start point in most cases
than it is to work off of a 90. If I want a 22.5 degree angle, I just
set the saw to 22.5 and give up and move over to the RAS that'll
actually hold my setting.

AHEM... If I want a 22.5 degree angle, I just set the saw to 22.5 or
-22.5 and don't have to do the math and figure out if I need 112.5 or
67.5?

I believe you have the answer right there. ;~) But really you want a
67.5 angle.... If the saw was marked correctly. But as you said, it
makes bringing the measurements you took to the saw, easier.


To tell you the truth I never thought about this much until Ron Paulk
mentioned how all miter saws were incorrectly marked.
